Fibres which pass through genu of internal capsule are:
**Core Concept**
The internal capsule is a deep structure in the brain that contains both ascending and descending tracts. The **genu of the internal capsule** is the part that connects the anterior and posterior limbs. It plays a crucial role in conveying sensory and motor information.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general function of the genu. The genu of the internal capsule primarily contains fibres related to the **cortico-bulbar tract**, which is involved in the control of cranial nerve functions, including those related to facial expressions, eye movements, and swallowing.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option provided, it's challenging to address each incorrect choice directly. However, typically, incorrect options might include tracts or pathways that do not pass through the genu, such as those primarily involved in sensory or motor functions of the limbs.
**Clinical Pearl / High-Yield Fact**
The internal capsule is a critical structure for neurological function, and damage to it, such as in a stroke, can lead to significant deficits. The genu's role in cranial nerve function makes it particularly important for controlling facial and eye movements.
**Correct Answer:** Correct Answer: C. Corticobulbar fibres.
